(Wall Street Cheat Sheet) Sourcing products from Chinese factories has always been a cost-saving tactic of American companies like Walmart (NYSE:WMT), the largest U.S. retailer. However, as wages, energy costs and overseas demand continue to increase, Walmart is looking to domestic for products to stock its stores.

Walmart will spend $50 billion in the coming decade in an attempt to tap into an American supplier market where fewer disruptions in production occur and energy prices remain low. The company’s willingness to look within suggests the shipping and related costs are weighing on Walmart’s profit margin.
